STOVEPIPE CLEANER AND DAMPER.

Application filed December 9, 1912.

Specification of Letters Patent.

Patented Jan. 2'7, 1914. Serial No. 735,745.

Y '0 all ac/mm it may concern:

Be it known that I, VVILLIAM J. SEXTON, a citizen of the United States, residing at New Sharon, in the county of Mahaska and State of Iowa, have invented a new and useful Stovepipe Cleaner and Damper, of which the following is a specification.

My invention relates generally to stove and furnace pipes which enter the chimney either inclined or horizontally, becoming quickly filled with soot, and particularly to a cleaner and damper for such pipes.

The object of my invention is to provide a cleaner and damper which shall be cheap in construction and easily applied and thoroughly eflicient in the speedy removal of the soot from such stove and furnace pipes without removing them from the stove, furnace or chimney, or letting the fire go out.

Another object of my invention is to regulate the draft in such pipes.

Another object is to provide a stovepipe which will not enter a chimney so far as to check or shut off the draft of a stove or furnace.

With these objects in view my invention consists of the peculiar construction of the.

'arlous parts and in their novel combination and arrangement all of which will be fully described in detail and illustrated in the drawings forming a part of this specification.

In the drawings Figure 1 is a View of my invention as ready for use, showing the elbow, bushing-tube or sleeve, horizontal pipe, collar, thimble and part of chimney in vertical section, and the head of the extension and disk at the farther inner side of the chimney. Fig. 2, is a View of my invention in use as a cleaner in vertical longitudinal section showing the elbow, the bushing-tube or sleeve, its flange and rivets, the horizontal pipe its extension-and head, the disk, the rod, the knob or handle, the marking notch or groove and the conical valve, all referred to hereinafter. Fig. 3, is a side elevation showing the elbow, horizontal pipe and its extension and head, and the disk within the inner end of the pipe in use as a damper. Fig. I. is a detailed view in perspective of the elbow and its bushing-tube or sleeve, the horizontal pipe its extension and head. the disk, rod, valve and knob or handle, all of which are referred to hereinafter.

Similar letters and figures of reference indicate corresponding parts throughout all the views.

In carrying out my invention I employ a stove or furnace A, in the present instance an ordinary heating stove, a vertical stovepipe B, a stovepipe collar C, a Stovepipe thiinble D, and a chimney E, shown in Fig. l.

A stovepipe elbow F, connected with the upper end of the pipe B, is provided in its front portion with a bushing-tube or sleeve G, hereinafter called sleeve, its outer end projecting through an opening in the front portion of said elbow. The inner end of said sleeve G, is provided with a flange G, adapted to the inner surface of said elbow F, to which said sleeve is secured by rivets through said flange. Said sleeve G, is adapted to receive a rod hereinafter described and prevents said rod from wearing a slot in said elbow, and is located as low as practicable to avoid contact of the rod with the lower inner surface of the elbow F, and horizontal pipe hereinafter described. The outer end of the horizontal pipe H, is connected with the upper end of said elbow F, and the inner end of said pipe H, enters the chimney E, through said collar C, and thimble D, and at its inner end is provided with an extension H, preferably produced by cutting away the upper portion of said pipe H, beyond the inner end of said thimble D, to give draft to the stove or furnace A. Said extension H, answers as a guide to the disk hereinafter described, and at its inner end said extension is provided with a head H to prevent its warping or sagging by the heat, and the inner end of said extension is in contact with the farther inner side of the chimney E, so that the pipe H, cannot enter the chimney E, so far as to obstruct the draft.

To insure its easy movement the disk I, is considerably less in diameter than the inner diameter of the pipe H, but a part of the upper portion of said disk I, is cut away as at I, to give sufficient draft to prevent the escape of smoke and gas from the stove or furnace when my invention is in operation. At its cross-center said disk I, has the tubular formation I projecting from the outer face of the disk and is provided with an internal thread adapted to an external thread at the inner end of said rod J, which extends a little beyond the inner face of said disk I, and is hammered down like a rivet, as at J; said rod is thus rigidly secured within said disk as shown in Fig. 3. Said rod extends through and beyond said sleeve G, the diameter of which is sufiiciently greater than the diameter of said rod J, to permit the turning of said rod and its movement back and forth within said sleeve G, and the elevation of the outer end of said rod when said disk I, enters In order to prevent said sleeve from acting as a check-draft when not desired said rod J, outside of said elbow F, is provided with a conic valve K, adapted to close said tube G, as in Figs. 1, and 4. The outer end of said rod J, is provided with a knob or handle L, by means of which my device is operated. In its upper edge the handle L, is provided with a marking notch or groove L, in order that it may always appear which edge of the disk to use as a cleaner.

hcn my invention is in use as a cleaner the operator by means of the handle L, pulls the disk I, forward elevating the outer end of the rod J, as the disk enters the elbow F, thus the disk carries before it the soot within said pipe H, and elbow F, and deposits it into the pipe B, where it then falls into the stove or furnace. By turning the rod J, the disk I, may be brought in contact with the entire inner surface of the pipe H, and any soot that may have adhered thereto be removed.

When my invention is in use as a damper the disk I, is pulled forward until it enters that part of the pipe H, within the thimble D, thus checking the draft in greatest degree, and it is obvious that the draft is checked less and less as said disk is moved backward and that when said disk is in contact with the head H the draft is unobstructed.

I reserve the right to make such changes in form proportion and minor details of construction as fairly fall within the scope of my invention,

Having thus described my invention, what Copies of this patent may be obtained for five cents each,

said elbow F.

I claim and desire to secure by Letters Pat cnt, is-

1. In a stovepipe cleaner and damper, the combination with a stove or furnace, a vertical pipe, a collar, a thimble, and a chimney, a stovepipe elbow having a sleeve provided with a flange and rivets, a horizontal pipe having an extension provided with a head, a disk, a rod having its inner end threaded and secured within said disk, its outer end projecting through said sleeve, a conical valve secured to said rod adapted to engage with said sleeve and a knob or handle secured to the outer end of said rod, and having a marking notch or groove all for the purposes set forth.

2. In a stovepipe cleaner and damper the disk having part of its upper portion cut away, and tubular at its cross-center, the tube I projecting from its outer face, and having an internal thread, and having a rod threaded at its inner end and secured within the tube 1 and said rod having secured thereto a conic-valve, and at its outer end a knob or handle, having in its upper edge a marking notch or groove, all substantially as shown and for the purpose specified.

3. The combination, in a stovepipe cleaner and damper, of a stovepipe elbow having in its front portion a sleeve, a horizontal pipe having an extension provided with a head, a disk having a part of its upper portion cut away, and tubular at its cross-center, the tube projecting from its outer face and hav ing an internal thread, a rod having its inner end threaded and secured within the tubular portion of said disk, said rod having a conic-valve secured thereto and at its outer end having a knob or handle having a marking notch or groove, wit-h a collar a thimble and a chimney all for the purposes set forth.
